title: Comparison of the efficiency of photography-assisted shade selection to visual shade selection.
abstract: This study sought to compare the efficacy of digital photographs and graphic software for shade matching to that of conventional visual shade selection. Thirty-one postgraduate students were used and shade selection was analyzed through 1 of 4 different techniques: digital spectrophotometer, conventional visual shade selection, visual shade selection assisted by digital photography, and shade selection by color difference formulas and computer software. Shade selection done with digital photography and graphic software using color difference formulas offered better and statistically significant shade matching compared to conventional visual shade selection and visual shade selection assisted by digital photography.
